Title: Water purification to remove organic contaminants - by filtering using rubber particles as filtration medium
Inventor: RIEMENSCHNEIDER FRIEDRICH
IPC: C02F1/28
Filed: 1989-07-14
Abstract: A process for purification of water contaminated with organic substances comprises filtering out the organic contaminants using rubber particles as filter medium. USE/ADVANTAGE - The rubber particles have a greater affinity to harmful organic substances such as aliphatic, aromatic and chlorinated hydrocarbons than to water, so that the contaminants become attached to the surface of the rubber particles during the filtration and are removed from the water. The process is an improvement over the use of active carbon as filtration medium due to the difficulty of disposal of the spent active carbon and the higher cost of this. When the particulate rubber filtration medium is satd. with the adsorbed contaminant, it can be regenerated for re-use e.g. with steam or hot air or by vacuum evapn. The process is useful for purification of industrial waste waters, circulating cooling water, etc..

Patent DE-4121697-A1 (DE)
Inventor: ERBEL HORST
IPC: C07C17/38
Filed: 1991-06-29
Abstract: The invention relates to a process for the recovery of solvents or other substances, which are condensable, adsorbed in an adsorber (3). The adsorber (3) is first heated to a temperature which is below the decomposition temperature of the solvent, the adsorber space (2) is then sealed off from the surroundings and a high vacuum is applied to the adsorber space (2), as a result of which the solvent is desorbed. For some of the time that this high vacuum is applied, the temperature of the adsorber (3) is brought to a temperature which is above the decomposition temperature of the solvent. Despite this, no decomposition occurs under the conditions mentioned, but the high temperature permits an almost complete desorption of the solvent. Finally, the desorbed solvent is withdrawn from the adsorber space (2) and condensed. <IMAGE>
